Immutable, thread-safe version of Alphabetic Index.
Required Header
#include <utils_i18n.h>
Overview
This module provides thread-safe methods for bucketing, and random access to buckets and their properties, but does not offer adding records to the index.
Functions | |
| int | i18n_immutable_idx_create (i18n_alpha_idx_h index, i18n_immutable_idx_h *immutable_index) |
| Creates an immutable index object. | |
| int | i18n_immutable_idx_destroy (i18n_immutable_idx_h index) |
| Destroys the immutable index object. | |
| int | i18n_immutable_idx_get_bucket_count (i18n_immutable_idx_h index, int32_t *count) |
| Returns the number of index buckets and labels, including underflow/inflow/overflow. | |
| int | i18n_immutable_idx_get_bucket_index (i18n_immutable_idx_h index, char *name, int32_t *number) |
| Finds the index bucket for the given name and returns the number of that bucket. | |
| int | i18n_immutable_idx_get_bucket_label (i18n_immutable_idx_h index, int32_t bucket_index, char **label) |
| Returns the label string of the index-th bucket. | |
| int | i18n_immutable_idx_get_bucket_label_type (i18n_immutable_idx_h index, int32_t bucket_index, i18n_alpha_idx_label_type_e *type) |
| Returns the label type of the index-th bucket. | |
Typedefs | |
| typedef void * | i18n_immutable_idx_h |
| An i18n_immutable_idx_h handle. | |
Typedef Documentation
| typedef void* i18n_immutable_idx_h |
An i18n_immutable_idx_h handle.
Use i18n_immutable_idx_* functions to operate on i18n_immutable_idx_h objects.

Function Documentation
| int i18n_immutable_idx_create | ( | i18n_alpha_idx_h | index, |
| i18n_immutable_idx_h * | immutable_index | ||
| ) |
Creates an immutable index object.
- Since :
- 5.0
- Remarks:
- The created object should be released by the caller with the i18n_immutable_idx_destroy() function.
- Parameters:
-
[in] index The alphabetic index the thread-safe version of which is to be created [out] immutable_index The created immutable index object
- Returns:
0on success, otherwise a negative error value
- Return values:
-
I18N_ERROR_NONE Successful I18N_ERROR_INVALID_PARAMETER Invalid function parameter I18N_ERROR_OUT_OF_MEMORY Out of memory
| int i18n_immutable_idx_destroy | ( | i18n_immutable_idx_h | index | ) |
Destroys the immutable index object.
- Since :
- 5.0
- Parameters:
-
[in] index The immutable index to be destroyed
- Returns:
0on success, otherwise a negative error value
- Return values:
-
I18N_ERROR_NONE Successful I18N_ERROR_INVALID_PARAMETER Invalid function parameter
| int i18n_immutable_idx_get_bucket_count | ( | i18n_immutable_idx_h | index, |
| int32_t * | count | ||
| ) |
Returns the number of index buckets and labels, including underflow/inflow/overflow.
- Since :
- 5.0
- Parameters:
-
[in] index The immutable index object [out] count The number of index buckets
- Returns:
0on success, otherwise a negative error value
- Return values:
-
I18N_ERROR_NONE Successful I18N_ERROR_INVALID_PARAMETER Invalid function parameter
| int i18n_immutable_idx_get_bucket_index | ( | i18n_immutable_idx_h | index, |
| char * | name, | ||
| int32_t * | number | ||
| ) |
Finds the index bucket for the given name and returns the number of that bucket.
Use i18n_immutable_idx_get_bucket_label() or i18n_immutable_idx_get_bucket_label_type() to get bucket properties.
- Since :
- 5.0
- Parameters:
-
[in] index The immutable index object [in] name The string to be sorted into an index bucket [out] number The bucket number for the name
- Returns:
0on success, otherwise a negative error value
- Return values:
-
I18N_ERROR_NONE Successful I18N_ERROR_INVALID_PARAMETER Invalid function parameter
| int i18n_immutable_idx_get_bucket_label | ( | i18n_immutable_idx_h | index, |
| int32_t | bucket_index, | ||
| char ** | label | ||
| ) |
Returns the label string of the index-th bucket.
- Since :
- 5.0
- Remarks:
- The returned string should be freed by the caller with free() function.
- Parameters:
-
[in] index The immutable index object [in] bucket_index The bucket number [out] label The label string for the bucket
- Returns:
0on success, otherwise a negative error value
- Return values:
-
I18N_ERROR_NONE Successful I18N_ERROR_INVALID_PARAMETER Invalid function parameter I18N_ERROR_INDEX_OUTOFBOUNDS Desired position is out of bounds
